> It's hard to wrap your head around some behaviors

I've got a React maintenance and development project coming up in a few weeks. I'd love if you'd expand a bit on these points and maybe point to some relevant docs. You could potentially save me days or more of tail chasing. Thanks.



The biggest thing most people don't understand is that React re-renders recursively by default, regardless of whether any particular child component's props actually changed or not. Most of its behavior patterns follow from that one.

I have an extensive post called "A (Mostly) Complete Guide to React Rendering Behavior) that covers the concepts and nuances in detail:

Thank you.


Primarily the rules of hooks and what does and does not trigger a render or a unmount. If your project still uses class instead of function components, that's a potential target for refactoring.

> some relevant docs

Read the docs. All of them. React isn't that big.


Thank you. Neither of those topics are new to me. Great to know!
